Increases the buffer capacity to hold at least size elements updating ptr_ and capacity_.

Implements fmt::Buffer< T >.

 {
 std::size_t new_capacity = this->capacity_ + this->capacity_ / 2;
 if (size > new_capacity)
 new_capacity = size;
 T *new_ptr = this->allocate(new_capacity);
 // The following code doesn't throw, so the raw pointer above doesn't leak.
 std::uninitialized_copy(this->ptr_, this->ptr_ + this->size_,
 make_ptr(new_ptr, new_capacity));
 std::size_t old_capacity = this->capacity_;
 T *old_ptr = this->ptr_;
 this->capacity_ = new_capacity;
 this->ptr_ = new_ptr;
 // deallocate may throw (at least in principle), but it doesn't matter since
 // the buffer already uses the new storage and will deallocate it in case
 // of exception.
 if (old_ptr != data_)
 Allocator::deallocate(old_ptr, old_capacity);
}
